Don't have a proprietary driver neither.
Dlink seems to have added USB support.
I assumed that is proprietary but I guess that is only x86.

There is also an open source USB driver on github but I don't think it is
getting fixes like the lfinger github one.
https://github.com/neojou/rtw89-usb
The D-Link driver is for the rtl8822bu, not an rtl8852au. That would make it
for rtw88, not rtw89. BTW, it will not compile under kernel 5.16.0-rc3, but
the fixes would be minor.
Is this statement in the readme of neojou not correct?
"This driver is based on Realtek's rtw89 driver
<https://github.com/torvalds/linux/tree/master/drivers/net/wireless/realtek/rtw89>
in Linux main trunk. Or can refer to this lwfinger's github [rtw89]
(https://github.com/lwfinger/rtw89)"
That is correct. What has been done there, and in the equivalent rtw88-usb
version, is replace the PCI I/O calls with the equivalent USB library calls.
What cannot be determined outside the Realtek halls is whether there are changes
in the NIC chip itself between the two versions. Certainly, there are
differences between the setup of the rtl8192ce and the rtl8192cu. I would expect
the same here.
I checked the dlink link and it is for a wifi5 device.
I don't know how I got there. :-(
There is no linux driver from dlink for the USB wifi6 device. :-(
Oh well, maybe in 10 years. :-)
That driver is the usual collection of junk code published by the Realtek USB
group for years. That code base is used to generate drivers for Windows,
Linux, and FreeBSD.
A group is currently modifying the rtl8188eu driver in staging to convert it
into reasonable Linux shape. This one would take the same effort to make it
suitable.
"Chipset:/RTL8188EU/ Standard: IEEE 802.11n"
Would a good 8188eu driver make it easier to support wifi5 and wifi6 devices?
Not really. That hardware is wifi4 (802.11n) and has no higher capabilities. The
basic silicon and firmware could not handle the higher protocols.
The basic USB driver in the neojou repo should work, but I do not have an
rtl8852au device.
Maybe it'll be in kernel eventually. :-)
Perhaps. That will depend on the PCI group from Realtek deciding to tackle that
project.
